The scheme solves issues where meshes would no longer align properly after converting them to Nanite. It also solves the precision issues in clusters with triangles of non-uniform size.
By default the precision is heuristically selected by Nanite, but the user also has the ability to override with an explicit precision to solve issues or optimize for disk size.
Clusters store the coordinate components using the minimal number of bits required to span the range of values in the cluster.
Apart from fixing issues, the default quality seems no worse than before and is typically ~5-10% smaller than before.
Added Position Precision to the top left of Mesh viewer along with the other mesh stats.
Added Position Precision dropdown to Nanite import settings.
Added debug mode "r.nanite.visualize PositionBits" that shows the vertex position bit sizes for clusters.
New quantization code now updates float positions and cluster bounds to reflect the quantized coordinates.

- Preserve guid during save if static mesh bulkdata content hasn't changed to avoid triggering unnecessary rebuilds
- Make sure the next HLOD generation is going to use the HashAsGuid feature to avoid recompiling staticmesh that are generated if they are exactly the same as before
- 31m10s to 14m15s to cook P_Construct_WP with a warmed-up DDC

* General cleanup
* Removed ExtractImposterToRawMesh() which was overspecialized and not specifically handling Imposters
* Renamed remains of FRawMesh to MeshDescription

Prepared direct attribute access for deprecation, preferring use of APIs to access static mesh attributes.
Fixed recently merged Enterprise code to comply with new APIs.
Changed all tools to use triangle-centric iteration where possible.
Added new MeshAttributeArray APIs for querying attribute flags, and added a new Mandatory flag.
Various bug fixes.
